Electrical models for MEMS varactors including the e ect of dielectric charging dynamics are not available in commercial circuit simulators. In this paper a circuit model using lumped ideal elements available in the Cadence libraries, and a basic Verilog-A model, has been implemented. The model has been used to simulate the dielectric charging in function of time and its e ects over the MEMS ca...

Electrical charging during SIMS-analysis (secondary ion mass spectrometry) is a severe limitation for the analysis of non-conductive samples. In most cases this charging can be compensated with the aid of an electron gun. This is an already established method to analyze insulating samples. In this work results of a systematic study of electron gun charge compensation in our CAMECA ims5f ion mic...

one of the new methods for electrical powering of the bridge health monitoring systems is applying energy harvesting systems using bridge vibration. in this method, the piezoelectric material is employed for converting mechanical energy into electrical energy. the advantage of this method is based on not implementing the battery charging system. in previous research, some studies have been done...

this paper presents a formulation of unit commitment for thermal units integrated with wind and solar energy systems and electrical vehicles with emphasizing on mixed integer nonlinear programming (minlp). the renewable energy resources are included in this model due to their low electricity cost and positive effect on environment. as well as, coordinated charging strategy of electrical vehicle...

The surface of insulators accumulates charge during subject to high voltage stresses electrically.The surface charging causes deteriorations of electrical performance and durability of high voltage insulators in gas. In this paper, we describe a result of visual analysis of electric fields with accumulation charge on complex insulator surface to clear the effect of surface charging on the diele...

Electric vehicles (EVs) will play a central role in future road traffic. To cope with the limited range and long charging times of such vehicles, a public fast-charging infrastructure will be deployed to recharge EV batteries. A challenge in such an infrastructure is the high costs associated with electrical peak loads; a charging station along a busy highway may see hundreds of EVs per hour. D...
